Original close reason(s) were not resolved
Is there a simpler or alternate way to code the following C# sentence?
if (iValue >= 4 && iValue <= 10) {... other code ...}
Do I need to repeat the iValue twice?
I have seen a structure similar to _ = ...some code... but I am not familiar with that leading underscore?

With C#9 you can use:
if(iValue is >= 4 and <= 10)
{
Console.WriteLine("in range");
}

In my program it says the float value for how much currency the person has. Currently if its a huge number say 200,000,000, it displays it as "2E+08" When I would rather it display "200 Million" Any help would be appreciated

I am trying to figure out a way to generate each number between 2 other numbers. For example, if the first number is 7 and the last number is 12 I want to generate an array(?) of Int that would be Intarray {7,8,9,10,11,12}.
Is this possible?

I have two sting lists
List<string> list1=new List(){"1","2","3"};
List<string> list2=new List(){"1","2"};
What will be the easiest way to check if list1 contains the values in list2.

How about
list1.Except(list2).Any();

Try using
[listName].Except(SecondListName).Any();
This should work.
